üüüPower and efficiency: Audi presents new 3.0

TDI at Vienna Motor Symposium
· New three-liter V6 as "clean diesel" and Euro 6
classification
· Two versions with 160 kW (218 hp) and 200 kW (272 hp)
· 13 ultra models with extremely low fuel consumption in the
Audi lineup
Ingolstadt/Vienna, May 8, 2014  More powerful, more efficient and
cleaner than ever: Audi presents the latest generation of its 3.0 TDI
engine at the 35th International Vienna Motor Symposium May 8 and 9.
The V6 diesel boasts innovative solutions in many fields of
technology.
As Prof. Rupert Stadler, Chairman of the Board of Management of AUDI
AG, explains: "TDI engines are a central part of our technology
mix for the mobility of tomorrow. We have continued to perfect this
technology over several decades and believe there is still potential
for increasingy efficiency in the future too."
"The new 3.0 TDI substantiates our claim as the leader in diesel
technology," said Prof. Dr. Ulrich Hackenberg, Member of the
Board of Management of AUDI AG, Technical Development. "We have
led the competition ever since the first TDI engine 25 years ago, and
are constantly extending this lead with new ideas."
Audi offers the exhaust turbocharged V6 in two versions producing 160
kW (218 hp) and 200 kW (272 hp). It features a 90-degree cylinder bank
angle and a displacement of 2,967 cc. Peak torque is as much as 600 Nm
(442.5 lb-ft) depending on the model. Although the new 3.0 TDI is
significantly more powerful than its predecessor, it is  again
depending on the model  as much as 13 percent more fuel efficient.
The new V6 diesel is packed with numerous high-end features. The
piston rings and pins have been optimized for minimal friction. The
crankcase and the newly designed cylinder heads have separate coolant
loops. The updated, innovative thermal management system improves
efficiency even further. The turbocharger and the fully variable-load
oil pump have also been updated. For the first time in automotive
history, a NOx storage catalytic converter has been combined with a
diesel particulate filter and SCR injection in a single assembly.
üThe exhaust gas after-treatment integrated into the engine
package satisfies the most stringent of emissions legislation,
including the Euro 6 standard. It also reduces CO2 emissions by an
average of 15 grams (24.1 g/mi). This improvement earns the 3.0 TDI
the "clean diesel" suffix.
The Audi lineup offers a broad choice of diesel engines with four, six
and eight cylinders. It begins with the 1.6 TDI, includes the 2.0 TDI
and 3.0 TDI, and tops out with the 4.2 TDI producing 283 kW (385 hp)
and 850 Nm (626.9 lb-ft) of torque in the Audi A8 [7.4 l/100 km (31.8
US mpg), 194 g CO2 per km (312.2 g/mi)]. All of these engines combine
ample power with groundbreaking efficiency, particularly in the 13
ultra models currently available. The Audi A4 1.6 TDI ultra, for
example, consumes on average just 3.2 liters of fuel per 100
kilometres (73.5 US mpg) [85 grams CO2 per km (136.8 g/mi)]. These
same figures for the A4 2.0 TDI ultra are 4.0 liters per 100
kilometers (58.8 US mpg) [104 grams CO2 per km (167.4 g/mi)] and for
the A6 2.0 TDI ultra with S tronic 4.4 liters per 100 kilometres (53.5
US mpg) [114 grams CO2 per km (183.5 g/mi)].
Audi continues to honor a small tradition with the presentation of the
new 3.0 TDI engine at the 35th International Vienna Motor Symposium
taking place May 8 and 9 at the Congress Center Hofburg. The company
presented its five-cylinder TFSI engine here in 2009 and in 2010 the
(at that time) new 3.0 TDI. The premieres of the 3.0 TDI biturbo and
the new 1.8 TFSI followed in 2011. Audi presented the 4.0 TFSI in
2012, and the company first presented the V6 TDI for the Audi R18
e-tron quattro race car to the public at the 2013 Vienna Motor
Symposium.
"The Vienna Motor Symposium offers us an excellent stage for our
technologies," said Dr. Stefan Knirsch, Head of Engine
Development. "We can present our innovations and discuss them
here with experts from all around the world." Besides the new 3.0
TDI, Audi is also presenting another innovation in Vienna: a new
seven-speed dual-clutch transmission for models with longitudinal
engines and front-wheel drive. The latest- generation S tronic is
extremely sporty, yet very comfortable. The newly developed
dual-clutch transmission impresses with its high efficiency, reducing
CO2 emissions by as much as 10 grams per kilometer (16.1 g/mi).
